We all want to think the best of our partners, but sometimes, you canât shake the feeling something isnât quite right in your relationship.
On Reddit, people have been sharing the telltale signs that made them finally realise their partner was cheating on them.
The common theme among them? A sudden, unexplained change in their partnerâs behaviour.
Of course, if you spot one of these signs it doesnât necessarily mean your partner is being unfaithful.

1. âIf you havenât changed your behaviour at all but suddenly they are paranoid and accusing you [of] cheating.â

2. âBeing edgy or secretive about their phone calls.â

3. âI knew she was probably cheating on me when she all of sudden accused me of being clingy when I gave her a lot of space and less contact.â
4. âShe had a different brand of rubber in her purse, we hadnât used a condom in months.â

5. âThe one I remember was sleeping with her phone under her pillow, even when plugged in to charge.â

6. âFor me, I could tell he was growing increasingly distant. He would tell me I wasnât putting the effort into our relationship, but when I tried to be more attentive and loving, he would withdraw.â
7. âSudden, unexplained changes in hygiene, grooming, and personal fitness.â
8. âThey talk about that person a lot. They go to see them when they said they couldnât be out that night. They put that person over you.â
9. âMy high school boyfriend never saved phone numbers into his phone. He claimed he was just âtoo lazy.â Turns out the unsaved numbers belonged to his many, many side girls.â
10. âA real easy one is they come home and immediately hit the shower, but itâs not hot and they didnât hit the gym or do anything strenuous.â
11. âSheâs sitting around on her phone and when you sit next to her she immediately changes positions so you canât see her screen.â
12. âI went over to his place one day and noticed that he had put away/hidden any sign of me there - earrings taken off the nightstand, shampoo taken out of the shower and hidden in the cupboard.â
13. âWhen their friends and close family wonât look you in the eye any more. They know, but are in the awkward position of either doing the right thing or keeping quiet - and theyâve chosen to stay quiet.â
14. âFrom my experience, finding more reasons to be mad at you and blame you for things. He was getting so upset any time I made small mistakes to make our failed relationship my fault.â
